In the block chain of this specification description, can specifically include can cover appointing for assets object in supported object
The block chain network for type of anticipating.
For example, in traditional block chain, the object supported only includes usually account object and contract object, and at this
In specification, the object that can be supported block chain is extended, in such as account object and conjunction of the existing support of block chain
About on the basis of object, a kind of assets object is further expanded out.
Wherein, it should be noted that the type of the block chain of this specification description can be connection without being particularly limited to
Alliance's chain, other types of block chain (such as privately owned chain, publicly-owned chain etc.) that can also be other than alliance's chain.
Above-mentioned contract object can specifically include and be issued in block chain, and in block chain by the target members in block chain
Distributed data base (i.e. block chain account book) in include, the assets object for supporting block chain be managed intelligence close
About program.The user for accessing block chain can create an assets by way of calling above-mentioned contract object on block chain
Object, and complete on block chain the online management of assets object held.
For example, in one example, above-mentioned block chain can be specifically one by several financial machines as allied member
Alliance's chain that structure is constituted, in this case, the target members in block chain can be then to have assets object wound in alliance's chain
Build the financial institution as allied member of permission.A distributed intelligent contract platform can be built by alliance's chain,
The operator of the intelligence contract platform, the object type that can be supported the intelligence contract platform is extended, in existing branch
On the basis of such as account object and contract object held, a kind of assets object is further expanded out so that as allied member
Financial institution, can be created in platform a kind of new by issuing the form of intelligent contract (contract object) on block chain
The Asset Type of increasing, so access block chain user, can by call the intelligence contract create an assets object with
And complete the online management for the assets object held.
Wherein, it should be noted that in the present specification, the request initiated on block chain of user of access block chain
Type can refer to specifically the transaction (transfer) employed in traditional block chain.
For example, the user of access block chain can be by initiating a friendship for creating assets object in block chain
Easily, it has issued contract object in block chain to call and completes assets Object Creation；Alternatively, can also be by block chain
A newer transaction of state for completing assets object is initiated, to call the contract object issued in block chain to complete
The Asset State of assets object updates.
Certainly, the type for the request that the user of access block chain initiates on block chain, can also be specifically other than transaction
, instruction, message of the data structure with standard of other forms etc., in the present specification without being particularly limited to.With
Under each embodiment in, book will be illustrated for accessing request that the user of block chain initiates on block chain and be transaction.
Above-mentioned assets object may include intellectual capital object；Intellectual capital object is for safeguarding intellectual capital, the intelligence
Assets correspond to user in any type of real estate with the real world, and by intellectual capital object the intelligence are provided
Production capacity is enough suitable for being handled block chain, for example especially suitable for by modes such as intelligent contracts in block chain to this
Intellectual capital object is handled.Wherein, intellectual capital correspond to user real estate with the real world type, this
Without being particularly limited in specification；
For example, by taking above-mentioned block chain is the alliance's chain being made of several financial institutions as an example, in practical applications, Yong Huren
Assets under the line of meaning form；For example, fund, house property, stock, loan agreement, bill, accounts receivable etc. can be by managing the connection
The financial institution of node device on alliance's chain is packaged into the form of digital asset, creates and issues the distribution in alliance's chain
In database.
Below by way of specific embodiment, and combine " block chain object extension ", " contract object publishing ", " assets object
Create " and " conversion of assets object type ", the technical solution of this specification is described in detail.
1) block chain object extension
In the present specification, the operator of above-mentioned block chain can support block chain when building block chain network
Object be extended.
In traditional block chain (such as ether mill), the object that block chain is supported usually only includes account object and conjunction
About two class of object.And in the present specification, the object that can be supported block chain is extended, in existing account object and conjunction
An assets object is about further expanded out on the basis of object.
I.e. in the present specification, the object that above-mentioned block chain is supported may include account object, contract object and assets
The three classes such as object.In this way, for access block chain user for, in addition to can be completed on block chain account,
Other than the establishment of intelligent contract, a stroke numeral assets can also be created on block chain, and then can be by money with the real world
Production transforms into digital asset of the publication on block chain.
In a kind of embodiment shown, the object that above-mentioned block chain is supported still can be by following four classes attribute
Field is constituted：
Balance fields (address field), in traditional block chain (such as ether mill), the usual table of Balance fields
Show " remaining sum ", is used to indicate the quantity for the token that object is held.And in the present specification, it can be to the meaning of Balance fields
It is extended, the address information for the assets object for no longer indicating " remaining sum ", but being used to safeguard that object is held.Wherein, in reality
In, the address information of multiple assets object can be safeguarded in Balance fields.
When realizing, account object illustrated above, contract object and assets object can be by Balance words
The address information that assets object is added in section, to hold assets object corresponding with the address information.I.e. in the present specification, it removes
Other than account object and contract object illustrated above, assets object itself can also hold fictitious assets.
Storage fields, the various states (such as account status, contract state, Asset State etc.) for safeguarding object.
For example, by taking assets object as an example, the financial institution of the assets object is issued, or other had pair by what the financial institution specified
The executor for the permission that assets object is updated, can be by changing the content in Storage fields, to update the assets pair
The state of elephant.For example, by taking above-mentioned assets object is the digital asset for being packaged into the loan agreement assets under user's line as an example, when
The daily loan state of honouring an agreement of the user changes, and issues the financial institution of the assets object, or referred to by the financial institution
Fixed other executors with the permission being updated to assets object, the state that can be honoured an agreement based on the daily loan of user are become
Change, update is synchronized to the content in the Storage fields in the corresponding assets object of the digital asset.
Code fields, for safeguard object statement relevant the executions code of execution program (such as with it is code dependent respectively
The executable method of kind).I.e. in the present specification, for account object illustrated above, contract object and assets object,
Relevant execution program can be stated in object.
For example, for for the contract object that is managed to assets object, the assets that are managed with the contract object
The relevant any form of operation of object, can be in the form of executing program, in the Code fields of the contract object in advance
Statement subsequently can execute program, to complete corresponding operation by directly invoking these；For example, for assets object into
The execution program stated in the contract object of row management usually may include for creating the execution program of assets object, update
The execution program of assets object, execution program of assets transfer object, etc..
Wherein, it should be noted that above-mentioned Code fields are held in addition to that can safeguard that the execution program of object statement is relevant
Other than line code, such as call address of contract object can also be safeguarded, be the calling for needing to transmit calling the contract object
Parameter, etc..
Nonce fields, for safeguarding the counting for preventing block chain from Replay Attack occurs.The counting can be usually used for one
Prevent block chain from the random number or pseudo random number of Replay Attack occurs.
2) contract object publishing
In a kind of embodiment shown, above-mentioned block chain can be specifically one by several gold as allied member
Melt alliance's chain of mechanism composition.In this case, the target members in block chain can be then to have assets pair in alliance's chain
The financial institution as allied member as creating permission.
A distributed intelligent contract platform can be built by alliance's chain, and there is assets object in alliance's chain
The financial institution of permission is created, can be created in platform by the form of the intelligent contract (contract object) of publication on alliance's chain
Build a kind of newly-increased Asset Type.
When realizing, each financial institution in alliance's chain can be registered as the allied member of alliance's chain first, obtain connection
A pair of of the public key and private key that alliance's chain returns.Public key is by the account address as each financial institution in alliance on the face；Private key is by conduct
Unique key of each financial institution's operation account.It secondly, can be by alliance's chain for each financial institution for the chain that coalizes
Operator carrys out the permission that unified authorization creates assets object.It, can be with after financial institution achieves the permission for creating assets object

The second Asset Type as that in addition, can also state this request conversion.
And the node device in block chain is when executing the transaction, can by call publication on block chain with it is upper
It states the corresponding contract object of the second Asset Type and the assets object of above-mentioned first Asset Type is converted into the money of Second Type
Produce object.
In a kind of embodiment shown, the contract pair corresponding with above-mentioned second Asset Type on block chain is issued
As in, other than it can state to create the execution program of assets object in advance, can also in advance it state for Asset Type
Conversion rule between the execution program and above-mentioned first Asset Type and above-mentioned second Asset Type converted.
Wherein, the specific rules content of above-mentioned conversion rule, in the present specification without being particularly limited to；For example, one
In kind embodiment, above-mentioned conversion rule can specifically include the assets object of above-mentioned first Asset Type, and conversion becomes valence
It is worth the assets object of identical second Asset Type.The side for the transaction that i.e. user can be by initiation for converting Asset Type
The assets object of first Asset Type of user's statement is converted into the assets pair for being worth identical second Asset Type by formula
As.
Certainly, in practical applications, can also include that other conversions are advised other than conversion described above rule
Then；For example, by the assets object of above-mentioned first Asset Type, conversion becomes the assets pair of identical second Asset Type of number
As, etc.；It is no longer enumerated in the present specification.
Execution logic corresponding to the above-mentioned execution program for being converted to Asset Type, in the present specification also not
It is particularly limited, it is self-defined that those skilled in the art can be based on the progress of actual demand；For example, in some cases, on
Stating and executing program is stated in advance in Code fields in contract object, for describing above-mentioned conversion rule
Execute code.
In this case, node device is executing assets object progress assets class of the transaction to above-mentioned first Asset Type
When type is converted, the execution program for being converted to Asset Type stated in above-mentioned contract object can be called, being based on should
The above-mentioned conversion rule stated in contract object, by the assets object of the above-mentioned first kind, conversion becomes above-mentioned second assets class
The assets object of type；Then, the execution program for creating assets object stated in above-mentioned contract object, base are further called
In above scaling results, the assets object of second Asset Type is created, by the assets object of above-mentioned first Asset Type
Be converted to the assets object of the second Asset Type.
For example, being that the assets object of above-mentioned first Asset Type is scaled value identical second with above-mentioned conversion rule
